I worked in a bike shop in the late 70's.....we used to sell a lot of that kind of "accessory".
I was not a fan of them then, and I still isn't, ain't, aren't.
The high sissy bar with the diamond pattern always reminds me of the chopper craze....it just didn't look right on a standard style motorcycle (Cruisers had not yet been created). They were really tacky with the blue, gold or red metal flake vinyl!
To pull the Sissy bar look off properly....I expect Peanut tanks, extended forks, and ape hangers are a necessity. I am also not exactly sure how you are going to adapt this to your bike - most of these used the fender or seat and shock mounts....and your shocks are really wide apart compared to what this sissy bar requires.
This is the closest thing I could find...so you might see how it would look.
